Tropospheric ozone and black carbon (BC) contribute to both degraded air quality and global warming. We considered ~400 emission control measures to reduce these pollutants by using current technology and experience. We identified 14 measures targeting methane and BC emissions that reduce projected global mean warming ~0.5°C by 2050. This strategy avoids 0.7 to 4.7 million annual premature deaths from outdoor air pollution and increases annual crop yields by 30 to 135 million metric tons due to ozone reductions in 2030 and beyond. Benefits of methane emissions reductions are valued at $700 to $5000 per metric ton, which is well above typical marginal abatement costs (less than $250). The selected controls target different sources and influence climate on shorter time scales than those of carbon dioxide-reduction measures. Implementing both substantially reduces the risks of crossing the 2°C threshold.

Rising atmospheric vapor pressure deficit (VPD)-a measure of atmospheric dryness, defined as the difference between saturated vapor pressure (SVP) and actual vapor pressure (AVP)-has been linked to increasing daily mean near-surface air temperatures since the 1980s. However, it remains unclear whether the faster increases in daily maximum temperature (T) relative to daily minimum temperature (T) have contributed to rising VPD. Here, we show that the faster rise in T compared with T over land has intensified VPD from 1980 to 2023.

The rapid increase in population has driven the demand for fossil fuel energy, contributing to increased carbon emissions that ultimately accelerate global warming and climate change. Battery storage systems have many advantages over conventional energy sources. However, they face limitations such as energy storage, cost, and environmental hazards that come with the use of chemical binders.

Urbanization and climate warming have contributed to global amphibian declines in recent decades, and amphibians are particularly vulnerable to warming because temperature influences their physiological processes across all life stages. Tadpole responses to warming in tropical climates are relatively understudied, and previous studies demonstrated species-specific responses to warming temperature. Warming ponds may quicken tadpole development and increase thermal tolerances, but increasing local temperatures push populations towards their physiological limits.

Heat stroke (HS), a life-threatening heat-related disorder, is characterized by a rapid elevation of core body temperature exceeding 40 °C, accompanied by central nervous system (CNS) dysfunction and multiple organ dysfunction syndrome (MODS). With the escalating impact of global warming, the incidence of HS has risen progressively, posing a significant threat to global health. The CNS is one of the primary target organs in HS, and its injury mechanisms involve intricate interactions among inflammatory cascades, oxidative stress, programmed cell death, and blood-brain barrier (BBB) disruption.

Early warning enables precautional control measures of CyanoHABs within water bodies and in water works, and it becomes operational with high frequency in situ data (HFISD) of water quality and forecasting models by machine learning (ML). However, the acceptance of early warning systems by end-users relies significantly on the interpretability and generalizability of underlying models, and their operability.
